Water Hammering Solutions Please
We live on the 5th floor in a Co Op building in Brooklyn. Lately the radiator goes on at 6 AM and we start to hear banging between the floorboards until 6:20 AM when the radiator turns off. This is the only time we hear this water hammering sound, the 20 mins the radiator turns on first thing in the morning. Its loud enough to wake us up in the morning. We don't hear the noise during the day. We have a baseboard-style radiator.
Our super came and all he did was change the air valve in our radiator, but the water hammering noise still occurred the next morning.
Can the problem be that the water level is set too high? Is there water built up in places were it shouldn't be? We really just want a morning on uninterrupted sleep. Any thoughts/solutions would be greatly appreciated.
